Product Description:

Bosch Rexroth Indramat designs the DKR02.1-W300B-BE32-01-FW for the DKR Drive Controllers series. The module acts as a three-phase servo amplifier that links motion commands from a PLC to a corresponding motor, supplying regulated current for precise axis positioning, coordinated speed profiles, and consistent torque in automated production equipment. It integrates directly into rack-mounted automation cabinets and reduces the need for external relay stages by providing closed-loop current control in a single housing. In automated cells, it serves as the power stage between the control system and the motor so the axis can follow commanded acceleration and speed with repeatable response.

It accepts motion commands on the SERCOS interface, a fiber-optic fieldbus that transmits cyclic setpoints and status data in real time. An internal resistor assembly is provided, and the unit is supplied with bleeder, so regenerated energy is dissipated inside the controller during rapid deceleration. Continuous output capability reaches 300 A, allowing the controller to drive high-torque spindle or gantry axes without current foldback. This current capacity also supports brief load surges seen in stamping presses and heavy transport systems. Component temperatures are controlled by air cooling with a built-in blower, and exhaust air exits at the top of the enclosure. Motor position signals are processed through digital servo and resolver feedback, allowing the drive to close high-resolution loops while still accommodating legacy resolver-equipped motors.

The control algorithms correspond to function numeric version 01 and hardware design version 1. The controller is assigned to line series 02 within the product line. These identifiers are used to identify the unit version and keep diagnostics consistent across matching modules. They also indicate which control revision is present in the drive.
